解方程︳x+2︳+︳3x-1︳=9
解方程︳x+2︳+︳3x-1︳=9
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
解方程:2x+9/x+3 - 1/x-3 = 5 - 3x-2/x
解方程:x-1/x+2 +9/(x+2)(x-1)=3/x-1
解方程:(x-2)(x^2-6x-9)=x(x-5)(x-3)
解方程 3x/x×x-1+x×x-1/3x=5/2
解方程:2x(x-1)-x(3x+2)=-x(x+2)-12
解方程 x(2x-4)+3x(x-1)=5x(x-3)+8
x/(x-2)+(x+1)/(x-6)=2x/(x-3) 解分式方程
解方程 (3x+1)(3x-1)=(x+2)(9x-4) 2(x-3)(x-2)-(x+3)²=(x-1)(x
解方程(3x^2+9x+7)/(x+1)-(2x^2+4x-3)/(x-1)-(x^3+x+1)/(x^2-1)=0
解方程:1\x(x+1)+1\(x+1)(x+2)+.+1/(x+8)(x+9)=2x+3\x(x+9)
